Exports

When the world price is above equilibrium, the country will export the product, which is when we sell our products to other countries.


  • In the diagram above, at the world price of $12, the domestic supply is
    50
    units and the domestic demand is only
    30
    units so this country can export the difference between supply and demand to other countries.
  • The exports are equal to the excess
    supply
    .
  • In the diagram above the exports =
    50 - 30 = 20

Wize Concept
Remember the consumer surplus is the area above the price and below the demand.

  • WIthout trade, the price is
    $10
    so the consumer surplus is the triangle above that (A + B)
  • With trade, the price is
    $12
    and domestic consumers are buying a quantity of
    30
    so consumer surplus is the triangle above that price and quantity (A).


Wize Concept
Remember producer surplus is the area below the price but above the supply.

  • Without trade, the price is
    $10
    so the producer surplus is the triangle below that (C).
  • With trade, the price is
    $12
    and domestic producers are selling a total quantity of
    50
    so producer surplus is the triangle below that price and quantity (B + C + D). We can summarize all this below:

Practice: Exports

Consumers would be worse off, domestic producers would be better off, and more trade would take place when a country starts to:
